  using specific proportions of yellow, cyan and magenta light
  any of the above


5)The term "Bars and Tone" refers to:
    a video and audio test signal
  a digital video signal format

  video refresh rates
  colour temperature


7)Vectorscopes are primarily used to check:
    the luminance signal
  the chrominance signal
  voltage levels
  colour temperature



8)If you reduce the blue level on a video picture, an average scene would appear to be:
    pinker
  a darker blue
  yellower
  magenta


9)If you desaturated a video picture of a red object, it would appear to be:
    pink
  a darker red
  cyan
  a richer shade of red


10)A light which is described as having a "colour temperature" of 10,000 degrees Kelvin is going to give off light:
    which is perfectly white
  that has a greenish look to it
  with a spectral content at the red end of the scale
  with a spectral content at the blue end of the scale


11)A light which is described as having a "colour temperature" of 2,000 degrees Kelvin is going to give off light:
    which is perfectly white
  that has a greenish look to it
  with a spectral content at the red end of the scale

18)Stereophonic microphones pick up stereo sound by using:
    one microphone for the left channel and one for the right

  neither 1 or 2
  either 1 or 2


19)When talking about audio signal levels:
    Mic Level will be lower than Line Level

  Mic Level will be higher than Line Level


20)The most common connector used for interfacing broadcast quality audio signals is called:
    an RCA connector
  a BNC connector
  an XLR connector
  a Triax connector


21)If a particular PAL picture is identified with a timecode reading of 01:02:08:18, then the picture that occurs eight frames later (assuming it's an unbroken recording) will be:
    01:02:08:24
  01:02:14:18
  01:02:09:01
  01:02:16:18



22)Timecode is used to:

  all of the above


23)The control track is used to:

  control the longitudinal motion of the videotape
  stop the tape from causing "head-clogs"
  all of the above
  none of the above


24)When in pause mode, a videotape recorder:
    continuously "reads" the same frame of video and displays it on the monitor
  wears away at the videotape, thus permanently damaging it
  wears away at the video heads, thus permanently damaging them
  all of the above
  none of the above
